Juden-chan is the name given to a group of special girls who use electricity to cheer up suicidal people in an alternate dimension. Plug (our heroine) has a device that can tell her people's level of depression (A being worst, F being happiest). Since they are from a different dimension, she can fly, pass through things, and pull magic plugs out of power pole transformers. Plug tries her best but encounters a boy who can both see and touch her (usually with a baseball bat). Unfortunately for Plug, his sister is her assignment and she has to get past him to 'charge' her up. (Source: ADB)

And right when Mayu moves in at Shungo's place, the super-wealthy school council president Houjou Reika begins to care for that boy - to the degree that she works as a maid in his mansion...
